i prefer the better answer though.

The answer to your question is: ( -10, 9)

Step-by-step explanation:

Equations given             - 8x - 9y = -1

                                                  y = 9

Substitute "y" in the first equation

                                      - 8x - 9(9) = -1

                                      - 8x - 81 = - 1

                                      - 8x = 81 - 1

                                      - 8x = 80

                                      x = 80 / -8

                                      x = -10

Point ( - 10, 9)
